CONOCEPHALINAE. 



This sub-family is represented by only one genus in Nova Scotia, characterized 

 as follows: 



CONOCEPHALUS < Thumb erg . 



The vertex of head projects forward and slightly upward in the form of a rounded 

 tubercle, the sides of which are hollowed out to receive the basal joints of the antennae. 

 Face round and oblique; eyes comparatively large and sub-globose; prosternal spines 

 weak; tegmina long, very narrow; stridulating organ well developed; light brown in 

 color with transparent centre; hind femora long, stout at base, unarmed beneath; ovi- 

 positor straight. 



Conocephalus fasciatus DeGeer — Fig. Ill 



This insect commonly known as the "slender meadow grasshopper" is the smallest 

 Locustid and is more commonly found on low lying marshes or meadows. 



The general color is a pale green tinged with brown, especially the legs and anten- 

 nae. The tegmina are of a pale straw color. A very dark brown band is present on the 

 head extending back from the fastigium to the posterior margin of the pronotum. The 

 head, thorax and legs often bear many minute red spots. 



Head with face very oblique. Vertex with fastigium extending forward and 

 slightly upward into a rounded tubercle. Eyes sub-globose. Face and cheeks rounded. 

 Pronotum with both anterior and posterior margins broadly rounded. Disk rounded 

 laterally and crossed by one or more faint lines. Median carina absent; lateral carina 

 rounded; lateral lobes deeper than long; prosternum with two small spines; tegmina 

 shorter than hind wings and very narrow; stridulating field small; arcuate vein promin- 

 ent. First two pairs of legs about equal in size and very slender; front coxa produced on 

 the outside into a flattened spine which extends over the trochanter. Hind legs of 

 medium length, femora swollen at base. All the femora are grooved on the under sur- 

 face to receive the tibia. 



All tibiae armed with strong black spines, the posterior ones bearing the greater 

 number. The legs are all sparsely covered with minute hairs; cerci of the male some- 

 what swollen at the base and toothed on the inner margin. The subgenital plate of 

 male bears two very small stylets at its distal end. Ovipositor straight and consists of 

 four very much flattened plates. 



This insect appears to be very common in all parts of the province, but never ap- 

 pearing in such numbers as to cause any noticeable damage.
